Republican Congressman Darrell Issa is condemning comments by California GOP gubernatorial hopeful Tim Donnelly in which he has tried to tie his Indian-American rival to fundamentalist Islamic law.

Issa said Thursday the comments and posts on social media are "hateful and ignorant garbage."

Donnelly, a state assemblyman who is popular with the tea party, has repeatedly said this week that rival Neel Kashkari supported Shariah banking code when he was a senior official at the U.S. Treasury Department in 2008. On Facebook, Donnelly posted a link to a banking seminar hosted by the department during which Kashkari, a Hindu, delivered opening remarks.

Issa, who describes himself as an Arab-American of Lebanese Christian descent, says the behavior should disqualify Donnelly from holding any office.

Donnelly did not immediately respond to a request for comment.
